I've had multiple 270's for most of my hunting & reloading life & there are plenty of powders that all work well; I've also loaded some loads for shorter range hunting with 130's in the 2400 FPS range that work fine too.

But like you, for shorter range work I went to a 45-70.

Powders that all work well in the 270 are:

RL-19, 22, 16, 23, 17........26 but I haven't used 26.
Norma 204, 205, MRP
H-4350 & 4831SC
IMR-4350, 4831, 7828SSC
Win StaBall 6.5, 780

If you decide to download, use something at least as fast as H-4350 or faster.
